public String delResolution(int id)
{
try
{
ConMan con = new ConMan();
Statement stmt = con.logOn().createStatement();
String msg = "";
String sql = "delete from ledger where id="+id;
if (stmt.execute(sql))
{
msg = "Delete failed";
} else
{
msg = "Delete successfully";
}
con.logOff();
return msg;

catch (SQLException e)
{
return "Delete. SQL error " + e.getMessage();
}
catch (java.lang.NullPointerException ne)
